Vilon vs Semax
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Vilon is a synthetic dipeptide (Lys-Glu) derived from the thymus gland extract Thymalin. The shortest immune-regulatory peptide known, Vilon modulates T-cell and NK-cell function, extends lifespan in animal models, and shows epigenetic anti-aging activity. It is one of the Khavinson peptide bioregulators.
- Semax is a synthetic heptapeptide derived from ACTH developed in Russia. It is a potent nootropic that enhances memory, focus, and provides neuroprotection. Approved in Russia for cognitive disorders, stroke recovery, and traumatic brain injury.
- Half-Life
- Very short as a free dipeptide; effects mediated via gene regulation
- Minutes (but effects persist for hours via BDNF induction)
- Admin Route
- SubQ, Oral
- Intranasal, SubQ
